There are indications that palpable fear currently pervades the Nigerian Immigration Service, NIS, over the issuance of entry visa to ISIS chief, Ahmed Al Assir, in Lebanon to visit Nigeria, Vanguard reports.

This is coming against the backdrop of reports that President Muhammadu Buhari has ordered a full scale investigation into the circumstances surrounding the granting of visa to the terrorist, who had been on the wanted list of several governments around the world.

Al Assir was reportedly arrested at Lebanon airport on his way to Nigeria through Egypt. He is been accused by the Lebanese judiciary of involvement in the killing 17 Lebanese soldiers and have sentenced him to death.

According to the report, a reliable source in the State House, informed the newspaper that the President was worried about the development and that the Buhari government will not stand by and watch while a para-military agency in charge of visa frustrates government’s efforts to stamp out terrorism from the country.

Relevant government agencies are believed to have been ordered to explain how the wanted terrorist was issued with a valid Nigerian visa.

“The reported arrest of the wanted terrorist is a huge embarrassment to Nigeria and the President has directed that the matter should be investigated. The embassy in Lebanon has been directed to furnish the ministry with details of how the man got the visa. The National Intelligence Agency Officer has been directed to provide details of what happened,” the officer said.

Similarly, officials of the NIS were seen in several meetings on Wednesday, apparently to deliberate on the development which sources say is capable of resulting to a lot of “reactions.”

According to a staff of the service at the NIS headquarters, quoted by the report, the management was toying with the idea of a major shakeup especially at the visa department to prevent a recurrence.
